Featured New Bluetooth Sodium Ion 12 Volt Battery

I took that picture of PriusCamper just before I bought the salty 12v battery to install in my 2007 Honda Civic hybrid. I am pretty excited about the idea that I won't be running into 12v startup problems with the Civic once I get this installed. I will post some pics. I know... it's a honda, but hey, it's a hybrid that is getting a cool upgrade. I look forward to installing the battery app so that I can actually keep an eye on the battery condition, make changes to optimize for my vehicle and all the other things this app can do. Big Thank You to PriusCamper for all the help with keeping my hybrids running!

 

Nifty! Sound like a good idea.
Guess there's an update to the Dr. Prius app for the 12v battery?
I replaced mine in May 2022... But I might get one, just because...

 

I seem to have this exact same battery from an ebay seller. Is there anyway to disable the light from always being on? Once I press the power off button it switches to 3v mode. Which I think is good when being away for like a month to save from high self discharge. But you would have to use door key to enter the car. Also can anyone test the voltage at rest? I'm getting 16.8v which is very unusual if nominal is 13.2v for sodium ion.

 

I will probably get Jack's Sodium ion traction batteries soon once my existing Toyota modules starts to show it's wear. So far it's still doing fine. All these years with the nickle plated bus bars too.

 

I doubt you have the "same" battery, from ebay.
What light?
When do you get 16.8 volts?

Are you putting this is a Prius?

 

Hi @PriusV17, very interesting, can you send me the link to the eBay listing?

Our 12v battery use the famous/expensive/reliable JK BMS that allow user to monitor and update configuration to the battery. The resting voltage is adjustable and the default setting is at 13.2v. FYI.

 

This seller is not showing consistent information. That's why I didn't install it yet. But the 12v battery looks identical and the app looks identical. Attached are the screenshot of my specs from that app and the links to the seller.

Specs look the same are yours Jack. But he is calling it LiFePO4 but it looks like Sodium Ion specs. Same exact looking battery just different sticker. Same app.



Here is the 12v:

He sold sodium ion batteries for traction modules also:

Don't put that in your Prius. It's not designed for it.
It could be a very costly mistake!

Get the Sodium 12v battery from Jack.
And the Sodium Hybrid Battery too.

 

I retested again with a different tester. And now it looks normal. Could have been a fluke with my first tester. Notice the icon on left side of first tester. Probably an error with tester.

 

Please, post photos when your electrical system fries.....

 

Jack, hope all is good with you. It's been years since we met. Still flying RC's? I've been flying night drones a lot recently. I will get back into RC's in the future. I have an F-14 Tomcat waiting to fly

 

Why would a 13.01 volt battery fry the electrical system??? Please explain why it would.

The Prius DC to DC converter outputs 14.1 volts when charging the 12v battery, and it does not fry the 12v electrical system!

 

Hello,

I am considering purchasing the NexPower 12V battery from Jack and have a few questions:

1. Can I use this battery in a 2016-2019 RAV4 Hybrid (Gen-4)? The RAV4 uses a standard Yuasa S46B24R, similar to the Prius Gen-2.

2. On the product page, there is an option to select a vehicle generation:

• 1997-2009 Prius Sodium-Ion
• 2009-current Prius Sodium-Ion

Is there any difference between these two options?

Thank you for your help!

 

Perhaps you should contact Jack for those questions....
Get it straight from the source.

 

The same battery in lead acid costs (which only lasts 4 years or less in my case) costs over $250. These $175 (plus shipping/tax) Sodium-Ion batteries or LFP should last the life of the car. I'm waiting for my existing 12v battery to die before I swap it. Like the Youtube guy video says. It's most likely the wiring or electronics that causes fires, but not the battery chemistry itself. So let's hope they have good electronics and wiring

 

It's quite fascinating how the state of charge (SOC) of Sodium-Ion batteries can be estimated.

With traditional AGM batteries, you can simply check the voltage to determine whether it's time to charge or drive. This is particularly important for people who work from home and only drive short distances once a week.

From what I understand, Sodium-Ion batteries tend to maintain a relatively constant voltage (similar to LFP batteries) until they are 80-90% discharged. Based on my experience with LFP batteries, the Battery Management System (BMS) typically starts to detect current draw once it reaches around 1-2 amps.

However, when you park the car with the alarm on, the current draw can be as low as 50-150 mA, which often goes undetected by the BMS. As a result, you can't accurately determine the SOC since the voltage remains nearly constant, and the BMS isn't sensitive to such small currents. This means the real battery's SOC is also not visible through Bluetooth monitoring.

Has anyone had experience with SOC estimation on NexPower Sodium-Ion batteries? I'm particularly interested in finding ways to avoid missing the ideal charging or driving window, ensuring the battery is charged before it runs out of power.

 

FYI, I can purchase a lead acid AGM battery at my local Walmart on the east cost for $169 + tax. The battery warranty is 4 years.

It looks like the NexPower Energy 12V batteries only have a 1 year warranty.

How many years do you think the batteries will last?
